This might help people understand what I am building, this is not the body I am using, this is a similar body I found. Mine is older and original.


As you can see by this pic hopefully there is not much room behind the rear doors to move the axel around, the only place for it to go and use the fenders is about a foot from the rear, which leaves a very short leaf, and only a few options for holding the axel in place, I was hoping the ladder bars would work as they are accessible to get, but since all are in agreement they won't I will see about finding the 4 bar link.
Again thanks for all the responses. you guys are great
